Depression is the leading mental health—related cause of the global burden of disease and is the focus of World Health Day 2017. Despite robust evidence of the effectiveness of interventions ranging from self-care to clinical interventions, the vast majority of people with depressive symptoms do not receive any care. The majority of persons meeting the binary diagnostic criteria for depression have mild to moderate symptoms that most often do not need clinical interventions. A staged model, from wellness to distress to disorder, offers a hybrid between binary and dimensional approaches to classifying depressive symptoms, with specific interventions delivered through distinct delivery platforms addressing each stage.
